Abstract:
Forty genotypes were screened against gall midge, yellow stem borer, leaf folder and whorl maggot infestation. The experiment was conducted in research cum instructional farm of Shaheed Gundadhoor College of Agriculture and Research Station, Jagdalpur, Bastar (C.G.) during Kharif, 2022. In the screening of rice genotypes against major insect pests, genotype MRST 20221-1 was found to be moderate resistant (score ‘3’) against gall midge and whorl maggot, while resistant (score ‘1’) against stem borer and leaf folder incidence. Genotype MRST 20221-6 was moderate resistant (score ‘3’) against gall midge and whorl maggot, resistant (score ‘1’) against leaf folder while highly resistant (score ‘0’) against stem borer incidence. Genotype MRST 20221-15 was found to be moderate resistant (score ‘3’) against gall midge, resistant (score ‘1’) against whorl maggot, highly resistant (score ‘0’) against stem borer and leaf folder incidence. Genotype MRST 20221-35 had moderate resistance (score ‘3’) against gall midge, resistance (score ‘1’) against whorl maggot and leaf folder, while highly resistance (score ‘0’) against stem borer incidence. Genotype MRST 20221-38 was moderate resistant (score ‘3’) against gall midge, while resistant (score ‘1’) against whorl maggot, leaf folder and stem borer infestations.
